8. Remove the pilot valve cartridges only if necessary
due to a known or suspected problem. After remov-
ing pilot valves, use a hex to remove the cartridges
(102), then remove cartridge o-rings (103). If
stripped, use two screwdrivers to screw out the cartridge.
NOTE: Do not remove undamaged pilot valve
cartridges.

Torque Instructions
NOTE: Fluid cover and manifold fasteners have a
thread-locking adhesive patch applied to the threads. If
this patch is worn, the screws may loosen during operation. Replace screws with new ones, or apply mediumstrength (blue) Loctite or equivalent to the threads.
If fluid cover or manifold fasteners have been loosened,
it is important to torque them using the following procedure to improve sealing.
NOTE: Always completely torque fluid covers before
torquing manifolds.
Start all fluid cover screws a few turns. Then turn down
each screw just until head contacts cover. Then turn
each screw by 1/2 turn or less working in a crisscross
pattern to specified torque. Repeat for manifolds.
Fluid cover and manifold fasteners:
100 in-lb (11.3 N•m)
Retorque the air valve fasteners (V) in a crisscross pattern to specified torque.
Air valve fasteners:
55 in-lb (6.2 N•m) for plastic center sections
80 in-lb (9.0 N•m) for metal center sections
c. Supply a minimum of 20 psi (0.14 MPa, 1.4 bar)
air pressure to the air valve. Shop air may be
used. The diaphragm will shift so the second
fluid cover will seat properly. Keep air pressure
on until the second fluid cover is attached.
d. Attach the second fluid cover (3). See Torque
Instructions, page 18.
e. Remove the air valve and the tool (302), replace
the gasket (108), and reattach the air valve. See
Torque Instructions, page 18.
NOTE: If you are replacing the diaphragms but not the
air valve, you must remove the air valve and gasket, put
the tool in place of the gasket, and put the air valve back
on to get the air pressure needed for proper installation
of the second fluid cover. Remember to remove the tool
and replace the gasket when finished.
8. Reassemble the ball check valves and manifolds as
explained on page 14.
